LncRNA-SNHG16 predicts poor prognosis and promotes tumor proliferation through epigenetically silencing p21 in bladder cancer.	More and more evidences have ensured the crucial functions of long non-coding RNAs (lncRNAs) in multiple tumors. It has been discovered that lncRNA-SNHG16 is involved in many tumors. Even so, it is still necessary to study SNHG16 comprehensively in bladder cancer. In terms of our study, the level of SNHG16 both in the tumor tissues and cell lines was measured and the relationship among SNHG16, clinicopathological traits and prognosis was explored. Interference assays were applied to determine the biological functions of SNHG16. It was discovered that the level of SNHG16 was evidently enhanced both in tissues and cell lines of bladder cancer. Patients with highly expressed SNHG16 suffered from poor overall survival. Multivariable Cox proportional hazards regression analysis implied that highly expressed SNHG16 could be used as an independent prognostic marker. It could be known from functional assays that silenced SNHG16 impaired cell proliferation, owing to the effects of SNHG16 on cell cycle and apoptosis. Finally, mechanism experiments revealed that SNHG16 could epigenetically silence the expression of p21. The facts above pointed out that lncRNA-SNHG16 might be quite vital for the diagnosis and development of bladder cancer, and could even become an important therapeutic target for bladder cancer.	bladder
Risks and complications of transurethral resection of bladder tumors in patients receiving antiplatelet and/or anticoagulant therapy: a retrospective cohort study.	BACKGROUND: Information on the safety of transurethral resection of bladder tumors (TURBT) in patients receiving anti-thromboembolic drugs is currently lacking. This study aimed to evaluate the clinical safety of TURBT in patients receiving anti-thromboembolic agents compared with patients not taking these agents and patients who interrupted their use perioperatively. METHODS: We retrospectively analyzed data for patients who underwent TURBT at Jichi Medical University Saitama Medical Center from September 2013 to August 2016.Patients who underwent surgery while receiving antiplatelet and/or anticoagulant drugs were allocated to the continuation group, those who interrupted these drugs comprised the interruption group, and those who did not use these agents were designated as the control group. We compared the patient characteristics, hemoglobin levels, and complications among the three groups. RESULTS: A total of 174 patients were analyzed including 19, 18, and 137 in the continuation, interruption, and control groups, respectively. There were no significant differences in patient and tumor characteristics, apart from age, among the three groups. Decreases in hemoglobin levels were similar in the continuation, interruption, and control groups (-0.50 g/dl, -0.40 g/dl, and -0.50 g/dl, respectively).Significantly more patients in the continuation group experienced clot retention compared with the control group (21% vs 5%, p = 0.03). Large tumor size tended to be a risk factor for clot retention in the continuation group (p = 0.07). No patient in the continuation or interruption group required blood transfusion, compared with two patients (1%) in the control group. No patients in any of the groups experienced cardiovascular events during their hospital stay or required rehospitalization for hematuria after discharge. CONCLUSIONS: TURBT can be performed safely in patients who continue to take antiplatelet and/or anticoagulant agents, without increasing the risks of severe hemorrhage and blood transfusion. However, the risk of postoperative clot retention may be increased in these patients.	bladder
[Early Diagnosis of Squamous Cell Carcinoma of the Urinary Bladder Reached by Routine Abdominal Ultrasonography in a Patient on Self-Catheterization : A Case Report].	A 69-year-old woman was referred to our department for refractory cystitis. Incomplete emptying of the bladder was observed, and symptoms did not improve after medication. Clean intermittent catheterization was initiated. Two years after introduction of catheterization, a mass in the bladder dome was detected by routine abdominal ultrasonography. She was diagnosed with malignant tumor of the bladder diverticulum based on cystoscopy, computed tomography, and magnetic resonance imaging. Partial cystectomy and lymph node dissection was performed following transurethral resection of the bladder tumor. Histopathology revealed squamous cell carcinoma and no signs of lymph node metastasis. She is alive and recurrence-free 28 months after surgery.	bladder
A systematic review of exercise and psychosocial rehabilitation interventions to improve health-related outcomes in patients with bladder cancer undergoing radical cystectomy.	OBJECTIVE: Summarizing the evidence on the effects of pre- and postoperative exercise and psychosocial rehabilitation interventions on patient-reported outcomes (PROs) and physical fitness in bladder cancer patients undergoing radical cystectomy. DATA SOURCES: The Cochrane Central Register of Controlled Trials, MEDLINE, Embase, Web of Science and the Physiotherapy Evidence Database were searched independently by two authors from inception until 10 November 2017. Cited references of the studies and citing references retrieved via Web of Science were also checked. REVIEW METHODS: Randomized controlled trials (RCTs) and non-randomized studies assessing effects of exercise and psychosocial interventions in bladder cancer patients undergoing radical cystectomy were eligible. Primary outcome measures were PROs and physical fitness. Risk of bias was assessed using the Cochrane Collaboration tool and the Newcastle-Ottawa Scale. RESULTS: Five RCTs (three exercise and two psychosocial studies) and one non-randomized psychosocial study comprising 317 bladder cancer patients were included. Timing of the intervention was preoperative ( n = 2), postoperative ( n = 2) or both pre- and postoperative ( n = 2). Positive effects of exercise were found for physical fitness ( n = 3), some health-related quality-of-life (HRQoL) domains ( n = 2), personal activities in daily living ( n = 1) and muscle strength ( n = 1). Psychosocial interventions showed positive effects on anxiety ( n = 1), fatigue ( n = 1), depression ( n = 1), HRQoL ( n = 1) and posttraumatic growth ( n = 1). Quality assessment showed most shortcomings with sample sizes and strong heterogeneity was observed between studies. CONCLUSION: The evidence relating to the effects of exercise in bladder cancer is very limited and is even less for psychosocial interventions.	bladder
Familial Cancer Clustering in Urothelial Cancer: A Population-Based Case-Control Study.	BACKGROUND: Family history of bladder cancer confers an increased risk for concordant and discordant cancers in relatives. However, previous studies investigating this relationship lack any correction for smoking status of family members. We conducted a population-based study of cancer risks in relatives of bladder cancer patients and matched controls with exclusion of variant subtypes to improve the understanding of familial cancer clustering. METHODS: Case subjects with urothelial carcinoma were identified using the Utah Cancer Registry and matched 1:5 to cancer-free controls from the Utah Population Database. Cox regression was used to determine the risk of cancer in first-degree relatives, second-degree relatives, first cousins, and spouses. A total of 229 251 relatives of case subjects and 1 197 552 relatives of matched control subjects were analyzed. To correct for smoking status, we performed a secondary analysis excluding families with elevated rates of smoking-related cancers. All statistical tests were two-sided. RESULTS: First- and second-degree relatives of case subjects had an increased risk for any cancer diagnosis (hazard ratio [HR] = 1.06, 95% confidence interval [CI] = 1.03 to 1.09, P < .001; HR = 1.04, 95% CI = 1.02 to 1.07, P = .001) and urothelial cancer (HR = 1.73, 95% CI = 1.50 to 1.99, P < .001; HR = 1.35, 95% CI = 1.21 to 1.51, P < .001). Site-specific analysis found increased risk for bladder (HR = 1.69, 95% CI = 1.47 to 1.95, P < .001), kidney (HR = 1.30, 95% CI = 1.08 to 1.57, P = .006), cervical (HR = 1.25, 95% CI = 1.06 to 1.49, P = .01), and lung cancer (HR = 1.34, 95% CI = 1.19 to 1.51, P < .001) in first-degree relatives. Second-degree relatives had increased risk for bladder (HR = 1.35, 95% CI = 1.2 to 1.5, P < .001) and thyroid cancer (HR = 1.18, 95% CI = 1.03 to 1.35, P = .02). Spouses showed an increased risk for laryngeal (HR = 2.68, 95% CI = 1.02 to 7.05, P = .04) and cervical cancer (HR = 1.57, 95% CI = 1.13 to 2.17, P = .007). These results did not substantively change after correction for suspected smoking behaviors. CONCLUSION: Our results suggest familial urothelial cancer clustering independent of smoking, with increased risk in relatives for both concordant and discordant cancers, suggesting shared genetic or environmental roots. Identifying families with statistically significant risks for non-smoking-related urothelial cancer would be extremely informative for genetic linkage studies.	bladder
Emerging first line treatment options for bladder cancer: a review of phase II and III therapies in the pipeline.	The treatment of urothelial carcinoma (UC) had remained unchanged for several years until the recent FDA approval of immune checkpoint inhibitors (CPIs) in the salvage setting. Novel dual CPI-CPI and CPI-chemotherapy combinations are now being investigated aggressively as first line therapy for metastatic disease. Areas covered: We discuss the recent insights into the tumor biology of UC, which may impact the prognosis as well as assist in developing precision medicine. This is followed by an overview of existing treatment including conventional chemotherapy as well as the trials that led to the recent approval of PD-1 and PD-L1 inhibitors. Ongoing phase II and phase III trials developing PD-1/PD-L1 inhibitors, CTLA-4 inhibitors and VEGF inhibitors as first-line therapy are discussed. Expert opinion: The treatment paradigm for the first-line therapy of UC is expected to shift from conventional platinum-based combination chemotherapy towards novel therapy incorporating CPI immunotherapy. Finding the right combination of drugs in the appropriate disease setting and identifying the right patient population based on biomarkers are important questions to be answered. Another major challenge will be the financial burden associated with these new drugs.	bladder
mRNA, microRNA and lncRNA as novel bladder tumor markers.	Early detection of bladder cancer (BC) is essential for improvement of the patient's prognosis and general survival rates. Current diagnostic methods are still limited, so new specific and cost-effective biomarkers are emerging as the noninvasive tools in treatment decisions in recurrent BC. Gene expression and epigenetic profile can be analysed using quantitative real-time-PCR (qRT-PCR) method in urine, blood and tissue. This review provides an update of recent findings on BC molecular profile as novel markers in diagnosis and prognosis of bladder tumors. We describe mRNA-, microRNA- and lncRNA-based biomarkers involved in the BC detection, diagnosis, prediction of recurrence and monitoring after treatment.	bladder
Diagnostic Ureteroscopy Prior to Radical Nephroureterectomy for Upper Tract Urothelial Carcinoma Increased the Risk of Intravesical Recurrence.	OBJECTIVE: To assess the impact of diagnostic ureteroscopy (URS) prior to radical nephroureterectomy (RNU) on intravesical recurrence (IVR) in patients with upper tract urothelial carcinoma (UTUC). MATERIALS AND METHODS: A systematic literature search of the Medline, Embase, PubMed, and Cochrane library was performed in August 2017. Cumulative analyses of available hazard ratios (HRs) and their 95% CI were conducted using Stata version 12.0. RESULTS: Eleven studies including 4,057 participants were included, with a total of 1,403 patients diagnosed with IVR during the follow-up period. The pooled HRs of eight studies suggested that diagnostic URS prior to RNU significantly increased the IVR risk after RNU (HR 1.53, 95% CI 1.31-1.77; p < 0.001). However, the preoperative diagnostic URS was not associated with cancer-specific survival (HR 0.72; p = 0.11), metastasis-free survival (HR 1.09; p = 0.60) or overall survival (HR 1.12; p = 0.73). No publication bias was observed (Begg, p = 0.90; Egger, p = 0.71). CONCLUSIONS: Regardless, the diagnostic URS prior to RNU might increase the IVR risk in patients with UTUC. As ureteroscopy provides important prognostic and therapeutic value and guides decisions in UTUC, more future studies should be performed to find a novel way to mitigate the potential risk of IVR after RNU, such as chemoprophylaxis after endoscopy.	bladder
Dual Inhibition of PIK3C3 and FGFR as a New Therapeutic Approach to Treat Bladder Cancer.	Purpose: MPT0L145 has been developed as a FGFR inhibitor exhibiting significant anti-bladder cancer activity in vitro and in vivo via promoting autophagy-dependent cell death. Here, we aim to elucidate the underlying mechanisms.Experimental Design: Autophagy flux, morphology, and intracellular organelles were evaluated by Western blotting, transmission electron microscope, and fluorescence microscope. Molecular docking and surface plasmon resonance assay were performed to identify drug-protein interaction. Lentiviral delivery of cDNA or shRNA and CRISPR/Cas9-mediated genome editing was used to modulate gene expression. Mitochondrial oxygen consumption rate was measured by a Seahorse XFe24 extracellular flux analyzer, and ROS level was measured by flow cytometry.Results: MPT0L145 persistently increased incomplete autophagy and phase-lucent vacuoles at the perinuclear region, which were identified as enlarged and alkalinized late-endosomes. Screening of a panel of lipid kinases revealed that MPT0L145 strongly inhibits PIK3C3 with a K(d) value of 0.53 nmol/L. Ectopic expression of PIK3C3 reversed MPT0L145-increased cell death and incomplete autophagy. Four residues (Y670, F684, I760, D761) at the ATP-binding site of PIK3C3 are important for the binding of MPT0L145. In addition, MPT0L145 promotes mitochondrial dysfunction, ROS production, and DNA damage, which may in part, contribute to cell death. ATG5-knockout rescued MPT0L145-induced cell death, suggesting simultaneous induction of autophagy is crucial to its anticancer activity. Finally, our data demonstrated that MPT0L145 is able to overcome cisplatin resistance in bladder cancer cells.Conclusions: MPT0L145 is a first-in-class PIK3C3/FGFR inhibitor, providing an innovative strategy to design new compounds that increase autophagy, but simultaneously perturb its process to promote bladder cancer cell death.

Impact of age on outcomes of patients with non-muscle-invasive bladder cancer treated with immediate postoperative instillation of mitomycin C.	OBJECTIVES: To evaluate whether age affects the clinical benefit afforded by immediate postoperative intravesical instillation of mitomycin C in a contemporary cohort of patients with NMIBC. PATIENTS AND METHODS: A total of 4,258 patients with NMIBC treated with transurethral resection of the bladder with (n = 2,605, 61%) or without (n = 1,652, 39%) one immediate instillation of mitomycin C from 5 institutions (study period: 2000-2007) were included. No patients received adjuvant instillations. A multivariable Cox proportional hazards regression model adjusting for standard clinical and pathological features tested the potential interaction term between age and administration of mitomycin C with regard to disease recurrence. RESULTS: A total of 2,063 patients experienced disease recurrence with a median follow-up of 48 months for those who did not recur. In multivariable Cox regression analysis, immediate postoperative instillation of mitomycin C (HR: 0.62; 95% CI: 0.56-0.68; P<0.0001) and age (HR: 1.04; 95% CI: 1.00-1.09; P = 0.036) were associated with disease recurrence. We observed only slight decreases in recurrence-free survival with age irrespective of treatment administration of mitomycin C or not. CONCLUSION: We confirmed reduced disease recurrence rates associated with 1 immediate postoperative intravesical instillation of mitomycin C in NMIBC patients. The benefit on recurrence-free survival of a postoperative intravesical instillation was preserved across all ages and therefore age by itself should not be taken into consideration when deciding to use it.	bladder
Urothelial neoplasms in pediatric and young adult patients: A large single-center series.	PURPOSE: Bladder cancer is the sixth most common cancer in the United States, but is exceedingly rare in young patients, leading to a lack of accepted standards for diagnosis, treatment, and surveillance. We review our institutional experience with bladder urothelial neoplasms in pediatric and young adult patients summarizing presentation, treatment, and outcomes. METHODS: Surgical pathology records at our institution were searched for cases of urothelial neoplasms among patients ≤25 years of age treated between January 1997 and September 2016. Cases submitted exclusively for pathology review were excluded. Diagnoses were confirmed based on pathologic examination using the 2004 World Health Organization classification system. RESULTS: Thirty-four patients were identified with a mean age of 21.1 years (range 8-25 years), and median follow-up was 25.1 months (1-187 months). The male to female ratio was 1.83:1. The most common presenting symptom was hematuria (n=26; 76%). Diagnoses were invasive urothelial carcinoma (n=3), noninvasive urothelial carcinoma (n=24), PUNLMP (n=6), and urothelial papilloma (n=1). Noninvasive lesions were resected by cystoscopy, after which 12% (n=4) experienced complications (grade II or greater). One patient with stage IV invasive disease at diagnosis died, and 2 patients developed recurrences. Of those with noninvasive carcinoma, 29% (n=7) required repeat cystoscopy soon after initial TURBT at outside institutions, and 17% (n=4) had tumors downgraded from high-grade to low-grade after pathology review. CONCLUSION: Hematuria is the most common sign of bladder neoplasia in children and young adults and should be investigated by cystoscopy. The majority of urothelial neoplasms in these patients are noninvasive and can be successfully treated with transurethral resection. LEVEL OF EVIDENCE: Level IV (Retrospective study with no comparison group).	bladder
Desethylamiodarone-A metabolite of amiodarone-Induces apoptosis on T24 human bladder cancer cells via multiple pathways.	Bladder cancer (BC) is a common malignancy of the urinary tract that has a higher frequency in men than in women. Cytostatic resistance and metastasis formation are significant risk factors in BC therapy; therefore, there is great interest in overcoming drug resistance and in initiating research for novel chemotherapeutic approaches. Here, we suggest that desethylamiodarone (DEA)-a metabolite of amiodarone-may have cytostatic potential. DEA activates the collapse of mitochondrial membrane potential (detected by JC-1 fluorescence), and induces cell death in T24 human transitional-cell bladder carcinoma cell line at physiologically achievable concentrations. DEA induces cell cycle arrest in the G0/G1 phase, which may contribute to the inhibition of cell proliferation, and shifts the Bax/Bcl-2 ratio to initiate apoptosis, induce AIF nuclear translocation, and activate PARP-1 cleavage and caspase-3 activation. The major cytoprotective kinases-ERK and Akt-are inhibited by DEA, which may contribute to its cell death-inducing effects. DEA also inhibits the expression of B-cell-specific Moloney murine leukemia virus integration site 1 (BMI1) and reduces colony formation of T24 bladder carcinoma cells, indicating its possible inhibitory effect on metastatic potential. These data show that DEA is a novel anti-cancer candidate of multiple cell death-inducing effects and metastatic potential. Our findings recommend further evaluation of its effects in clinical studies.	bladder
Aberrant N-Glycosylation Profile of Serum Immunoglobulins is a Diagnostic Biomarker of Urothelial Carcinomas.	The aim of this study to determine whether the aberrant N-glycosylated serum immunoglobulins (Igs) can be applied as a diagnostic marker of urothelial carcinoma (UC). Between 2009 and 2016, we randomly obtained serum available from 237 UC and also 96 prostate cancer as other cancer controls from our serum bank and also obtained-from 339 healthy volunteers (HV)-controls obtained from community-dwelling volunteers in Iwaki Health Promotion Project. A total of 32 types of N-glycan levels on Igs were determined by high-throughput N-glycomics and analyzed by multivariable discriminant analysis. We found five UC-associated aberrant N-glycans changes on Igs and also found that asialo-bisecting GlcNAc type N-glycan on Igs were significantly accumulated in UC patients. The diagnostic N-glycan Score (dNGScore) established by combination of five N-glycans on Igs discriminated UC patients from HV and prostate cancer (PC) patients with 92.8% sensitivity and 97.2% specificity. The area under the curve (AUC) for of the dNGScore was 0.969 for UC detection that was much superior to that of urine cytology (AUC, 0.707) and hematuria (AUC, 0.892). Furthermore, dNGScore can detect hematuria and urine cytology negative patients. The dNGscore based on aberrant N-glycosylation signatures of Igs were found to be promising diagnostic biomarkers of UCs.	bladder
RalGPS2 is involved in tunneling nanotubes formation in 5637 bladder cancer cells.	RalGPS2 is a Ras-independent Guanine Nucleotide Exchange Factor (GEF) for RalA containing a PH domain and an SH3-binding region and it is involved in several cellular processes, such as cytokinesis, control of cell cycle progression, differentiation, cytoskeleton organization and rearrangement. Up to now, few data have been published regarding RalGPS2 role in cancer cells, and its involvement in bladder cancer is yet to be established. In this paper we demonstrated that RalGPS2 is expressed in urothelial carcinoma-derived 5637 cancer cells and is essential for cellular growth. These cells produces thin membrane protrusions that displayed the characteristics of actin rich tunneling nanotubes (TNTs) and here we show that RalGPS2 is involved in the formation of these cellular protrusions. In fact the overexpression of RalGPS2 or of its PH-domain increased markedly the number and the length of nanotubes, while the knock-down of RalGPS2 caused a strong reduction of these structures. Moreover, using a series of RalA mutants impaired in the interaction with different downstream components (Sec5, Exo84, RalBP1) we demonstrated that the interaction of RalA with Sec5 is required for TNTs formation. Furthermore, we found that RalGPS2 interacts with the transmembrane MHC class III protein leukocyte specific transcript 1 (LST1) and RalA, leading to the formation of a complex which promotes TNTs generation. These findings allow us to add novel elements to molecular models that have been previously proposed regarding TNTs formation.	bladder
